To all whom it may concern:

Be it known that I, JAMES NEILL, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Fluting Columns and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will-enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The present invention has reference generally to improvements in that class of apparatus used in the manufacture of fluted col- I umns for interior or exterior wood-work,

balustrades, and the like; and the invention relates, more particularly, to a novel arrangement and construction of a movable or traveling cutting means, the same operating automatically to cut flutes in a column of any desired lengths and furthermore, will cut flutes in a column of any desired outside or surface conformation.

The invention therefore has for its primary object to provide a novel cutting or fluting mechanism of the general character hereinafter set forth and a novel means for feeding the cutter or fluting device back and forth over the surface of the column during the cutting operation; and, furthermore, to provide means for automatically stopping the movement of the cutting means when a flute of the desired length has been made or cut in the surface of the column.

Another object of the present invention is to provide a means foradjusting vertically, the said movable or traveling cutting means and the mechanism for operating the same, to adapt the same for use in fluting columns of different and varying diameters.

Other objects of this invention not at this time more particularly mentioned will be clearly understood from the following detailed description of the said invention.

With the objects of the present invention in view, the said invention consists, primarily, in the novel mechanism for cutting flutes in columns and the like and, the invention consists, furthermore, in the various novel arrangements and combinations of devices and parts, as well as in the details of the construction of the same, all of which will be tion of the said device in cutting the flutes in the said column proceeds. Fig. 2 is a detail front elevation of the cutting means and the devices used for causing the same to travel or move in a re'ciprocatory manner over the column during the cutting operation. Fig. 3 is a plan view of the parts and devices illustrated in the front elevation in said Fig. 2. Fig. 4 is a side elevation of the cutting or fluting means and'its carriage, looking in the direction of the arrow 00, in Fig. 3. Fig. 5 is a longitudinal vertical section of the cutting means and its carriage, taken on line 55, in said Fig. 3, looking also in the direction of the arrow as. Fig. 6 is a detail vertical longitudinal section of an adjustable trip or release arm which is arranged upon the carriage of the said cutting means. Fig. 7 is a detail plan view of one of a pair of slidable bearings adapted to carry the main driving shaft of the device. Fig. 8 is a front elevation of one of a pair of slidable bearings adapted to carry the shifting or feeding mechanism of the cutting means, the parts mounted thereon being indicated in dotted outline. Fig. 9 is a cross-section of the same, said section being taken on line 99 in said Fig. 8, the worm-bearings shown in dotted outline in said'Fig. 8 being illustrated in full lines in this figure. Fig. 10 is a side elevation of the cutter or fluting device; Fig. 11 is a vertical longitudinal section of the same, taken on line 1111 in said Fig. 10, the knives of the cutter being shown in elevation; and Fig. 12 is a cross-section of the same, said section being taken on line 1212 in said Fig. 10, the knife-blades being removed in this view. Fig. 13 is a perspective view of one of the knife-blades of the cutter.

Similar characters of reference are emreference character 1 indicates a suitable base, such as a bench, table, or the like, upon which is secured the usual members 2 of a wood turning lathe, of any well-known and desirable construction, and held between said lathe-members 2 by means of the usual chucks or the spindles 3, is a turned column 4. One of said members 2 at one end of the lathe is provided with theusual hand-wheel 8, and with a graduated perforated disk 5, said disk being secured to the spindle 3. A lock-pin 6 engages with a perforation in the said disk 5 and locks the said column against turning, said pin 6 being actuated for withdrawal from the perforation in the disk by means of a pivot-device 7. The perforations of the disk 5 are arranged so as to correspond in number to the number of flutes desired to be cut upon the column, the latter being intermittently shifted or turned around to present its surface at intervals to the cutting means so that it may be provided with flutes equi-distant from each other, all around its outer surface of the column.

Secured upon the base or bed 1 and back of the lathe-members 2 are a pair of retaining sockets or bearings 9 in which are mounted the lower ends of a pair of vertical shafts 10,

said shafts having their upper portions arranged in a pair of sockets or bearings 11 which are secured to a cross-beam 121 of the ceiling or other suitable place. Slidably arranged upon each shaft 10 is a main bearing 12 which is provided with a forwardly-extending portion or arm 13 carrying an auxiliary bearing 14, substantially of the construction indicated in Fig. 7 of the drawings.

Mounted in the auxiliary bearings 14 of the main-shaft bearings 12, is the main or driving-shaft 15. Secured upon the said main or driving shaft 15 and between the bearings 14 is the extra wide-pulley wheel 16, collars 17 being suitably secured in fixed positions upon said shaft 15 to retain the shaft and its long pulley in their proper rotary positions between the bearings 14, as will be clearly evident. Upon one end of the main or driving-shaft 15 are a fast pulley 18 and a loose pulley 181 over which may be arranged the usual belt which serves to impart motion to the main or driving shaft 15 from an outside source of power. Loosely arranged upon each end of the main or driving-shaft 15 is a gearor sprocket wheel 19 provided with a hub 20 in which are clutchreceiving sockets 21, and slidably arranged upon the main or driving-shaft 15 and adapted to turn therewith is a clutch-member 22 of any usual or well-known form, said clutchmember being adapted to be thrown in e11- gagement with the gear or sprocket wheel 19 to turn the same. The shifting means for the said clutch-member 22 consists of a bearing 23 slidably arranged upon the vertical shaft 10, the said bearing 23 being provided with an outwardly extending arm 24 with the end of which is pivotally connected one end of a clutch-shifting lever 25, having a portion operatively connected with the member 22 for actuating the same in the usual manner.

Slidably arranged upon the vertical shafts 10 are other clamps 26, said clamps 26 being each provided with outwardly extending portions 27 which terminate in auxiliary clamps 28. Said clamps 26 are also provided with rearwardly extending members 29 formed with bearing-portions in which are rotatively arranged the respective endortions of a shaft 30, substantially as i ustrated. Attached to the front side of the outwardly extending portion 27 of each bearing 26 is a plate 31, said plate extending downwardly below the bottom of the said clamp 26, and being provided near one side with a hole or perforation 32 and near the other with a slotted opening 33. Pivotally secured upon each plate 31 by means of a rearwardly extending pin or lug 34, which extends through the hole or perforation 32 and a rearwardly extending pin or lug 35 which extends through the slotted opening 33, is a plate 36, said plate 36 being held in place by the nuts 37 which are screwed upon the screw-threaded free ends of the said pins or lugs 34 and 35. The plate 36 is provided with a pair of bearings 38 and an inwardly extending handle-portion 39, which is provided with a lug or stud 40. Mounted within the bearings 38 is a shaft 41 upon which is secured a worm 42, the free ends of the said shaft 41 being provided with gears or sprocket-wheels 43 each of which is connected by means of a block or link-chain 44 with the respective gears or sprocket-wheels 19 mounted on the main or driving-shaft 15. Rotatively arranged in each bearing 28 is a short shaft or spindle 45 each spindle carrying upon its front end a worm-gear 46, adapted to engage with the worm 42. Upon the rear end of said shaft or spindle 45 is a gear or sprocket wheel 47. These gears or sprocket wheels 47 are operatively connected by means of a link or block-chain 48.

The plate 31 is provided with a lug 49 upon which is pivotally arranged a catchlever 50, said lever being provided at its lower end with a hook or catch-piece 51, which normally engages with the lug or stud 40, to hold the plate 36 and its bearings 38 in such a position that the worm 42 is brought in engagement with the worm-gear 46. For the purpose of normally keeping the said catch-lever 50 in operative engagement with the said lug or stud 40 until such time as it is proper to release the same, there is provided a flat-spring 52, which is secured upon the plate 31, and has its free end in engagement with the upper portion of the catchlever 50, in a manner clearly illustrated and I and locked in position by means of the setas will be understood from an inspection of screws 82.

the drawings.

Slidably arranged upon the shaft 30, by means of bearings 53, is a cutter-carriage 54. The said cutter-carriage is provided with a bearing-plate 5 secured upon the upper side of the carriage, substantially as shown. The bearing-plate is provided with a centrally disposed rectangular opening 56, a pair of caps or bearing-members 57 being secured upon the under side of the said bearing-plate 55. Mounted in the bearings thus formed is a shaft or' spindle 58 upon which is secured a pulley 59 which extends up through the rectangular opening 56. Secured upon the free end of the said shaft 58 is a cutter-tool 60 comprising a pair of disks 61 and 62, said disk resting against a shoulder 63 formed on the shaft 58. Each disk 61 and 62 is provided with a groove or channel 64 extending diagonally across its face, and at right angles to the axis of the shaft 58, the bottom of said groove or channel 64 forming an acute angle. A pair of knives or cutting blades 65 are inserted in the said channels or grooves 64, the edges of the said knife or cutting blades 65 being made to form an acute angle 66 so as to conform with the angular bottom of the said channels or grooves 64. A washer 67 and a nut 68 are screwed upon the screw-threaded end of the shaft 58 and serve to draw the two disks 61 and 62 together and thus bind or look the knives or cutting blades 65 in their operative positions, between the disks 61 and 62. The said cutter-carriage 54 is provided with an upwardly extending portion 69 on its forward end to which is secured a handle 70, which is used to raise and lower the cutter-carriage into and out of engagement with the column, the cutter-carriage being adapted to swing or oscillate in a hinge-like manner with reference to the shaft 30 as an axis. A rib or crossbar 71 is formed on the up-turned portion 69 of the cutter-carriage 54 through which passes the shank of an adjusting screw 72 which engages with an upwardly extending lug 73 upon the bearing-plate 55, and serves to hold or look the same against any tendency to slip or move.

Extending from side to side of the cuttercarriage and on the under side thereof is another rib or cross-bar 74 provided with a bearing 75 in which is mounted a spindle which carries .a wheel 76. This wheel 76 may be used to travel over a guide or pattern of the conformation of the column to be cut when such a method is desirable.

Arranged at the opposite edges of the cutter-carriage 54 are suitable standards or brackets 77, upon each of which is secured by means of the bolt 7 8 and nut 79, an adjustable trip-arm 80 formed of a series of tubeportions 81 telescoped one within the other A pair of perforated ears or lugs 83 are .secured to one of the said standards or brackets 77, with which are pivotally connected the arms 84 of a belt-tightener, the pulley 85 of which is secured between the free ends of said arms 84, a spring 86 being attached at one end to one of the arms 84 and at its other end to the bearing-plate 55 to maintain the pressing engagement of the pulley 85 against a belt 87 which connects the pulley 59 with the pulley wheel 16.

Arranged above the two bearings 53 of the cutter-carriage 54 is a rib or cross-bar 88 which is provided with a lug or stud 89. The link or block chain 48 is joined together by a turn-buckle 90 which engages with right and left threaded screw-shanks 91 secured upon the ends of the chain, said turn-buckle 90 being adapted to take up the slack in the chain; and, furthermore, being provided with a centrally disposed hole or opening 92 with which engages the previously mentioned lug or stud 89, serves as a coupling or connecting member to operatively connect the said cutter carriage 54 with the said chain 48, the purposes which will be more clearly set forth hereinafter in the description of the operation of the machine.

In order to secure a vertical adjustment of the operative parts of the machine, so that it may be adapted to flute columns of various diameters, the following apparatus is provided. Each of the bearings 11 are provided with a lug or extension 93 which provide bearings for screw-threaded shafts 94 and 95, said shaft 94 being provided with a right handed screw-thread and said shaft 95 being provided with a left handed screw-thread. Referring now to Figs. 1, 3 and 7 of the drawings, it will be seen that the screw threaded shafts 94 and 95 extend through perforated and correspondingly screw-threaded perforations or holes formed in suitableextensions or lugs 96 and 97 of the respective elements or members which are provided with the bearing-portions 1'1 and 14, and the clamps 26 and rearwardly extending members 29. A pair of brackets or hangers 103 provided with bearings 104 are secured to the cross-beam 121 and mounted therein is a shaft 98, which is provided with a hand-wheel 99. Upon each end of the shaft 98 is secured a bevel-gear 100, each in operative engagement with a bevel-gear 101 secured upon each of the said screw-threaded shafts 94 and 95. It will be clearly understood that by turning the hand-wheel 99 to revolve the shaft 98 and its bevel-gears 100, the said bevel-gear 101 and the screwthreaded shafts 94 and 95 are caused to turn, and the threads of the shafts operating in the screw-threaded holes of the respective lugs or extensions 96 and 97 cause the bearings 14 and 23, and the clamps 26 and the rearwardly extending members 29, to rise or descend upon the vertical shafts 10, thus raising or lowering all the operative mechanisms of the device for the purposes above stated.

Having thus described in a general way the various parts and mechanical elements thereon imparts its motion to the cutter-tool 60, through the, belt 87, pulley 59 and shaft 58. One of the worms 42 is then brought in engagement with the worm-gear 46 on either the right or left hand side of the machine, according to the direction it is desired to move or shift the cutter carriage 54. When the worm 42 has thus been placed in its operative relation with the worm-gear 46, it is set in motion by shifting the clutch-member 22 in engagement with the gear or sprocket wheel 19, which causes it to revolve with the shaft 15, and through the medium of the chain 44, the gear or sprocket-wheel 43 and the shaft 41, the worm 42 is caused to revolve the worm-gear 46, which through the medium of its shaft 45 and the gear or sprocketwheel 47 operates the chain 48. The latter by means of the coupling-means adapted to connect it with the cutter-carriage 54, draws said cutter-carriage 54 from one side of the machine to the other, thus permitting the cutter-tool 60 to traverse the length of the column and cut the flute thereon. In order to stop the operation or movement of the cutter-carriage 54, when a flute of the required length has been cut in the column, the adjustable trip-arm 80 is set at the proper length to trip or throw out of engagement the catch-lever 50 with the lug or stud 40 when the cutter-carriage 54 reaches a certain point, thus causing the worm 42 to drop away from its operative engagement with the worm-gear 46, and thereby bringing the shifting or feeding mechanism to a full stop. Thus, by alternately operating the worm 42 on opposite sides of the machine, the cutter carriage 54 is caused to slide back and forth upon the shaft 30 in either direction, alternately, and as will be clearly evident.

The minor and detail operations of the parts and devices of the complete machine will be clearly understood from an inspection of the drawings, and need not, therefore, be more fully described.

, It will be readily understood from the fore going description, that the present invention provides a novel and effective device for fluting columns and the like, the flutings or channels being perfectly made, and a simple mechanism is the result which saves much time, labor and expense,in the production of such fluted, grooved or channeled columns.
